python异常捕获try except

python的异常处理机制设计的比较传统，在日常的开发中，基本满足我的需要

下面就python的异常，几点小小的讨论

tommy@lab3:~$ python
Python 2.5.2 (r252:60911, Jan  4 2009, 17:40:26)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 1/0
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ZeroDivisionError: integer division or modulo by zero
>>>
>>> try:
...     1/0
... except:
...     print "do something..."
...
do something...
>>>

2. try...finally

finally 里面只是执行完成try中的代码后，必须执行的代码，

即使是 try中有异常抛出，也是会去执行finally

>>> try:
...     1/0
... finally:
...     print "I just finally do something ,eg: clear!"
...
I just finally do something ,eg: clear!
Traceback (most recent call last):
